Traditionally MSYS bash has been inferior, but mostly because Cygwin remained under active development whereas MSYS didn&#39;t. MSYS forked from Cygwin version 1.3.3 and never re-synced, whereas MSYS2 resyncs with the Cygwin project regularly.

We don&#39;t have a &quot;sweet pacman like package manager&quot;, we have as direct a re-compilation of Arch Linux&#39;s pacman package manager as we could achieve.

MSYS2 doesn&#39;t have cygwin.dll but it does have msys-2.0.dll which does the same thing (and some more besides). Specifically, arguments that look like paths and the PATH env. var are converted to Windows form when running Windows-native software.

As for whether it&#39;s slower, I expect there&#39;d be very little difference but MSYS2 would be a tiny amount slower due to the extra conversion work. Then again, chances are you&#39;ll run more Windows-native software from within MSYS2 (such as MinGW-w64 compilers) than you would from Cygwin so that&#39;ll shift things back in MSYS2&#39;s favour.

As well as I understand, MSYS2 is a fork of Cygwin with main goal to provide possibility to use MinGW-w64 packages. That goal is achieved at expense of total number of available software. Compare list of that of [MSYS2](https://github.com/Alexpux/MSYS2-packages) and [Cygwin](https://cygwin.com/packages/).

Essentially, that’s all. So while you did not need to compile something under MinGW-w64, you would hardly have any reason to use MSYS2 rather than original Cygwin.

Given the newly announced iPhone 6 [screen sizes][1]:

    iPhone 6: 1334h * 750w @2x (in points: 667h * 375w)
    iPhone 6+: 1920 * 1080 @3x (in points: 640h * 360w)

I was wondering if there is code that allows me to detect which screen size the user&#39;s device is, so that I could adjust and size `UIImages` and other materials accordingly with the user&#39;s device. 

So far, I have been using the following:

    - (NSString *) platform{
        size_t size;
        sysctlbyname(&quot;hw.machine&quot;, NULL, &amp;size, NULL, 0);
        char *machine = malloc(size);
        sysctlbyname(&quot;hw.machine&quot;, machine, &amp;size, NULL, 0);
        NSString *platform = [NSString stringWithUTF8String:machine];
        free(machine);
        return platform;
    }
    
    - (NSString *) platformString{
        NSString *platform = [self platform];

As such, should I assume `iPhone7,1` and `iPhone7,2` are the iPhone 6 while `iPhone7,3` and `iPhone7.4` are the pluses? If anyone has more concrete way to tell it&#39;d be great, thanks.!

Traditionally MSYS bash has been considered inferior to Cygwin bash. 
The former was an ancillary tool inside MinGW intended for running autoconf scripts. 
But now there is  MinGW-w64 and MSYS2. The latter ships with a sweet pacman like package manager and elegant shells like zsh, so I wonder if there is still a gap in the emulation layer. 

While MinGW* applications are Windows native executables, MSYS2 software requires a POSIX-emulation layer, just like Cygwin does. At least to a casual user, it is hard to spot the differences between the two. 

- Which are the functional differences between the two emulation layers (if any)? 
- Which emulation is faster (more efficient)?

A recent vulnerability, [CVE-2014-6271][1], in how [Bash][2] interprets environment variables [was disclosed][3]. The exploit relies on Bash parsing some environment variable declarations as function definitions, but then continuing to execute code following the definition:

    $ x=&#39;() { echo i do nothing; }; echo vulnerable&#39; bash -c &#39;:&#39;
    vulnerable

But I don&#39;t get it. There&#39;s nothing I&#39;ve been able to find in the Bash manual about interpreting environment variables as functions at all (except for _inheriting functions_, which is different). Indeed, a proper named function definition is just treated as a value:

    $ x=&#39;y() { :; }&#39; bash -c &#39;echo $x&#39;
    y() { :; }

But a corrupt one prints nothing:

    $ x=&#39;() { :; }&#39; bash -c &#39;echo $x&#39;

    $ # Nothing but newline

The corrupt function is unnamed, and so I can&#39;t just call it. Is this vulnerability a pure implementation bug, or is there an intended feature here, that I just can&#39;t see?
 
## Update

Per Barmar&#39;s comment, I hypothesized the name of the function was the parameter name:

    $ n=&#39;() { echo wat; }&#39; bash -c &#39;n&#39;
    wat

Which I could swear I tried before, but I guess I didn&#39;t try hard enough. It&#39;s repeatable now. Here&#39;s a little more testing:

    $ env n=&#39;() { echo wat; }; echo vuln&#39; bash -c &#39;n&#39;
    vuln
    wat
    $ env n=&#39;() { echo wat; }; echo $1&#39; bash -c &#39;n 2&#39; 3 -- 4
    
    wat

…so apparently the args are not set at the time the exploit executes.

Anyway, the basic answer to my question is, _yes, this is how Bash implements inherited functions_.

I use scp shell command to copy huge folder of files.

But at some point of time I had to kill the running command (by Ctrl+C or kill).

To my understanding scp copied files sequentially, so there should be only one partially copied file.

**How can same scp command be resumed to not overwrite successfully copied files and to properly handle partially copied files?**

P.S. I know I can do this kind of stuff in rsync, but scp is faster for me for some reason and I use it instead.

I am trying to build some open source library. I need package management system to easily download the dependencies. At first I am using `MinGW+MSYS`. But the included packages are limited. Someone told me to use `MinGW-w64 + MSYS2`.

I downloaded the `mingw-w64-install` from [here][1]. When running, it reports the following error. How to fix it?

![enter image description here][2]


And btw, from the `MinGW-w64` download page, I see a lot of download links. Even Cygwin is listed. How `Cygwin` and `MinGW-w64` are related?

![enter image description here][3]


My current understanding is, in the time of `MinGW+MSYS`, MSYS is just a nice addon to MinGW, while in `MinGW-w64 + MSYS2`, MSYS2 is standalone and MinGW-w64 is just a set of libraries it can work with. Just like Cygwin can download many different packges.

How to install MinGW-w64 and MSYS2?

While I am aware of the option of [installing Pip from source](https://pip.pypa.io/en/latest/installing.html), I&#39;m trying to avoid going down that path so that updates to Pip will be managed by Cygwin&#39;s package management.

I&#39;ve [recently learned](https://stackoverflow.com/a/12476379/2489598) that the latest versions of Python include Pip.  However, even though I have recently installed the latest versions of Python from the Cygwin repos, Bash doesn&#39;t recognize a valid Pip install on the system.

Note that the installed Python 2.7.10 and Python 3.4.3 are both recent enough that they should include Pip.

Is there something that I might have overlooked?  Could there be a new install of Pip that isn&#39;t in the standard binary directories referenced in the $PATH?  If the Cygwin packages of Python do in fact lack an inclusion of Pip, is that something that&#39;s notable enough to warrant a bug report to the Cygwin project?

Why can&#39;t Git Bash run my executable?

I am not even sure I am asking the right question. Let me explain my situation:

This is about Git on Windows&amp;nbsp;7.

My company sets up the Windows user directory on a network drive, not on the local hard drive (for backup and other purposes beyond the scope of this question). I cannot change that policy.

I CAN have local files outside of that scheme however and that is how my Apache server is set up. Entirely local.

I installed Git. It installs Bash. When I fire up Bash and `cd ~` (change to the root directory) I find that it (the Bash root) points to my network user directory. I want it not to do that. I want  `~` to be elsewhere on my hard drive. I want it so that when I perform other operations such as installing a certificate, an SSH key, etc. its defaults will not automatically use that network directory.

I have searched in vain everywhere, and all I can find refers to answers that involve aliases, redirection, and the location $HOME points to. But that is not what I want at all.

The question is: Can I change that directory? And if so: How?

**UPDATE: So, $HOME is what I need to modify. However I have been unable to find where this mythical $HOME variable is set so I assumed it was a Linux system version of PATH or something. *Anyway*...**

I do have a &quot;profile&quot; file under `git/etc`. Here are the contents (notice no $HOME):
